The impossible key - help!

Hi guys, I'm new here.

I've been knocking my head against this all day and have been getting nowhere. Our regular post guy is tied up on another project and it has fallen to me to key some shots for a project with a very tight turnaround.

I'm working in AE CS6 with the native keying plugins.

I have several GS scenes featuring a blonde actress, all shot on a crop sensor DSLR and at least a stop under-exposed. The issue is that there doesn't seem to be sufficient definition between the screen and the hair tones to produce a clean key no matter what I try, especially as her hair is a little messy with clumps and strands sticking out from the main body and I can't roto out the offending areas either because her hair falls in front of her shoulders so I would end up with random strands appearing from nowhere on her body.



I've tried pushing the exposure, saturation, contrast etc to try and achieve more definition and every combination of tools I can think of, but it just ain't working and I have to choke the matte down to toonish levels before it even begins to address the noise.

Can any of you people offer any suggestions? I've got a day or so to turnaround 9 of these shots so a reshoot is out of the question, any advice you can offer would be much appreciated.

Cheers

Too late but i've heard people key out those thin hair and overlay
a patch static version of them from a good frame following
a two point tracker. And they get away with it in many cases.
